Description

Technical Field

[0001] This utility model relates to the field of laser ranging module technology, and in particular to a multi-mode switching laser ranging module. Background Technology

[0002] A laser rangefinder module is an electronic device that uses laser technology to measure distance. It emits a laser beam, measures the time it takes for the laser to travel from the emission point to the target object and back, and then calculates the distance to the target object based on the speed of light.

[0003] The above and existing technologies have the following drawbacks: the laser ranging module is not convenient to switch the shape of the emitted beam, which will affect the accuracy in some special measurement scenarios. For example, when it is necessary to measure a small target or a target with obstructions in a complex environment, the laser spot is too large. In addition to the reflected light from the target element, it will also receive reflected light from surrounding elements or chip substrates. These additional reflected light signals will interfere with the measurement, making it impossible to accurately obtain the distance between target elements.

[0004] Therefore, a multi-mode switching laser ranging module is proposed. Utility Model Content

[0007] The effect achieved by the above components is as follows: by setting an adjustment structure, it is easy to replace the perforated template with different sizes as needed, thereby switching the size of laser emission, thus ensuring accurate acquisition of the distance between target elements and improving the accuracy of measurement.

[0008] Preferably, the inner wall of the frame is fixedly connected to two first springs, one end of the first spring is fixedly connected to a rectangular plate, and both sides of the template are fixedly connected to extension plates.

[0009] The effect achieved by the above components is as follows: the pressure plate is removed from the surface of the template. At this time, the rectangular plate will push the extension plate with the help of the extension force of the first spring. The extension plate will drive the template to slide out of the frame with the help of the push force of the rectangular plate, thereby making it easier to remove the template from the frame.

[0010] Preferably, two rectangular holes are provided on one side of the frame, and a limiting block is slidably connected to the inner wall of the rectangular hole, and the limiting block is fixedly connected to the surface of the rectangular plate.

[0011] The effect achieved by the above components is that the movement of the rectangular plate will cause the limiting block to slide along the inner wall of the rectangular hole, and the rectangular hole will limit the movement path of the limiting block, thereby limiting the movement path of the rectangular plate and preventing the rectangular plate from coming out of the frame.

[0012] Preferably, a turntable is fixedly connected to the end of the threaded rod away from the pressure plate, and the vertical cross section of the turntable is in the shape of a cross.

[0013] The effect achieved by the above components is that the rotation of the turntable will drive the threaded rod to rotate, and the turntable facilitates the rotation of the threaded rod.

[0014] Preferably, the surface of the laser ranging module body is provided with a protective structure, the protective structure including a bracket, the bracket being fixedly connected to the surface of the laser ranging module body, a limiting arm being rotatably connected to the inner wall of the bracket, two circular holes being opened on the surface of the limiting arm, a pin being slidably passed through the surface of the bracket, the size of the pin being adapted to the size of the circular holes, and a cover plate being fixedly connected to one end of the limiting arm.

[0015] The effect achieved by the above-mentioned components is that by setting up a protective structure, it is easy to cover the connector on the surface of the laser ranging module body, thereby preventing the connector from being damaged by bumps when the laser ranging module body is not in use.

[0016] Preferably, a second spring is fitted onto the arc surface of the pin, and the two ends of the second spring are fixedly connected to the pin and the bracket, respectively.

[0017] The effect achieved by the above components is that the pin is inserted into the round hole with the help of the contraction force of the second spring. The second spring improves the stability of the pin inserted into the round hole and prevents the pin from coming out of the round hole due to shaking.

[0018] Preferably, a sealing ring is fixedly connected to one side of the cover plate, and the sealing ring is made of rubber.

[0019] The effect achieved by the above components is that the pressure plate will cause the sealing ring to fit tightly against the surface of the laser ranging module body. The sealing ring improves the airtightness of the fit between the cover plate and the laser ranging module body, thereby preventing dust from entering the connector from the gaps.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, by setting an adjustment structure, the template is inserted into the frame. When the template is fully inserted into the frame, the template will be aligned with the laser emitting head. At this time, the laser emitted by the laser emitting head will pass through the perforation, which makes it easy to replace the perforated template with different sizes as needed, thereby ensuring accurate acquisition of the distance between target components and improving the accuracy of measurement.

When the pressure plate rotates to a suitable angle, it will adhere to the surface of the laser ranging module body. At this time, the pressure plate will cover the connector, thereby preventing the connector from being damaged by bumps when the laser ranging module body is not in use. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] like Figure 1 - Figure 5 As shown, this utility model provides a multi-mode switching laser ranging module, including a laser ranging module body 1. A laser emitter 2 is mounted on the surface of the laser ranging module body 1, and a connector 3 is mounted on one side of the laser ranging module body 1. An adjustment structure 4 is provided on the surface of the laser ranging module body 1. By setting the adjustment structure 4, it is possible to easily replace the perforated template 406 405 with different sizes as needed, thereby switching the laser emission size and ensuring accurate acquisition of the distance between target elements, thus improving measurement accuracy. A protective structure 5 is provided on the surface of the laser ranging module body 1. By setting the protective structure 5, it is possible to easily cover the connector 3 on the surface of the laser ranging module body 1, thereby preventing the connector 3 from being damaged by impacts when the laser ranging module body 1 is not in use.

[0032] The specific settings and functions of its adjustment structure 4 and protection structure 5 will be explained below.

[0033] like Figure 2 and Figure 3As shown, the adjustment structure 4 includes two pillars 401, both of which are fixedly connected to the surface of the laser ranging module body 1. A frame 402 is fixedly connected to one end of the two pillars 401 away from the laser ranging module body 1. Threaded rods 403 are threadedly connected to both sides of the frame 402. A pressure plate 404 is rotatably connected to one end of the two threaded rods 403 that are close to each other. A template 405 is inserted into the inner wall of the frame 402. Two through holes 406 are opened on the surface of the template 405. Two first springs 407 are fixedly connected to the inner wall of the frame 402. A rectangular plate 408 is fixedly connected to one end of the first spring 407. Extension plates 409 are fixedly connected to both sides of the template 405. When the pressure plate 404 is removed from the surface of the template 405, the rectangular plate 408 will push the extension plate 409 with the force of the extension of the first spring 407. The extension plate 409 will drive the template 405 to slide out of the frame 402 with the push of the rectangular plate 408, thereby facilitating the removal of the template 405 from the frame 402. Two rectangular holes 410 are provided on one side of the frame 402. Limiting blocks 411 are slidably connected to the inner walls of the rectangular holes 410. The limiting blocks 411 are fixedly connected to the surface of the rectangular plate 408. When the rectangular plate 408 moves, it will cause the limiting blocks 411 to slide along the inner wall of the rectangular holes 410. The rectangular holes 410 limit the movement path of the limiting blocks 411, thereby limiting the movement path of the rectangular plate 408 and preventing the rectangular plate 408 from coming out of the frame 402. A turntable 412 is fixedly connected to the end of the threaded rod 403 away from the pressure plate 404. The vertical cross section of the turntable 412 is cross-shaped. The rotation of the turntable 412 will cause the threaded rod 403 to rotate, thus facilitating the rotation of the threaded rod 403.

[0034] like Figure 4 and Figure 3 As shown, the protective structure 5 includes a bracket 51, which is fixedly connected to the surface of the laser ranging module body 1. A limiting arm 52 is rotatably connected to the inner wall of the bracket 51. Two circular holes 53 are formed on the surface of the limiting arm 52. A pin 54 slides through the surface of the bracket 51. The size of the pin 54 is adapted to the size of the circular holes 53. A cover plate 55 is fixedly connected to one end of the limiting arm 52. A second spring 56 is sleeved on the arc surface of the pin 54. The two ends of the second spring 56 are fixedly connected to the pin 54 and the bracket 51, respectively. The pin 54 will be inserted into the circular holes 53 by the force of the contraction of the second spring 56. The second spring 56 improves the stability of the pin 54 inserted into the circular holes 53 and prevents the pin 54 from falling out of the circular holes 53 due to shaking. A sealing ring 57 is fixedly connected to one side of the cover plate 55. The sealing ring 57 is made of rubber. The pressure plate 404 will cause the sealing ring 57 to fit tightly against the surface of the laser ranging module body 1. The sealing ring 57 improves the sealing between the cover plate 55 and the laser ranging module body 1, thereby preventing dust from entering the connector 3 from the gaps.

[0035] The overall working principle is as follows: when it is necessary to switch the laser emission shape of the laser ranging module body 1, firstly, the turntable 412 is rotated. The rotation of the turntable 412 will drive the threaded rod 403 to rotate. The rotation of the threaded rod 403 will move within the frame 402 by means of the thread. The movement of the threaded rod 403 will drive the pressure plate 404 to move. After the pressure plate 404 moves to the appropriate position, the template 405 is inserted into the frame 402. The template 405 will drive the extension plate 409 to slide along the inner wall of the frame 402. When the extension plate 409... After moving to the appropriate position, the extension plate 409 will press against the rectangular plate 408, causing the rectangular plate 408 to move within the frame 402. The compression of the rectangular plate 408 will cause the first spring 407 to compress. The movement of the rectangular plate 408 will cause the limiting block 411 to slide along the inner wall of the rectangular hole 410. The rectangular hole 410 will then limit the movement path of the limiting block 411, thereby limiting the movement path of the rectangular plate 408 and preventing the rectangular plate 408 from detaching from the frame 402. When the template 405 is fully inserted into the frame... After the frame 402 is in place, the template 405 will align with the laser emitter 2. Then, the turntable 412 is rotated in the opposite direction. The threaded rod 403 moves within the frame 402 with the help of the turntable 412. The movement of the threaded rod 403 will cause the pressure plate 404 to move closer to the template 405. When the pressure plate 404 moves to the appropriate position, it will fit tightly against the surface of the template 405, thus limiting the position of the template 405. At this time, the laser emitted by the laser emitter 2 will pass through the frame 402. The laser beam passes through the hole 406. By replacing the template 405 with a different size of hole 406, the shape of the laser emission can be changed. When it is necessary to remove the template 405 from the frame 402, the pressure plate 404 is removed from the surface of the template 405. At this time, the rectangular plate 408 will push the extension plate 409 with the force of the extension of the first spring 407. The extension plate 409 will drive the template 405 to slide out of the frame 402 with the push of the rectangular plate 408, thereby making it easier to remove the template 405 from the frame 402.

[0036] When protection of connector 3 is required, first pull the pin 54. The pin 54 will slide within the bracket 51 and gradually disengage from the round hole 53. As the pin 54 moves, the second spring 56 will be stretched. After the pin 54 disengages from the round hole 53, rotate the pressure plate 404. The rotation of the pressure plate 404 will cause the limiting arm 52 to rotate within the bracket 51. The rotation of the limiting arm 52 will cause the pressure plate 404 to rotate, moving it closer to connector 3. When the pressure plate 404 rotates to a suitable angle, it will cause the sealing ring 57 to tightly adhere to the surface of the laser ranging module body 1. At this point, the pressure plate... 404 will cover the connector 3 to prevent the connector 3 from being damaged by bumps when the laser ranging module body 1 is not in use. The sealing ring 57 improves the sealing between the cover plate 55 and the laser ranging module body 1, thereby preventing dust from entering the connector 3 through gaps. At this time, the pin 54 is released, and the pin 54 will be inserted into the round hole 53 by the force of the second spring 56. The pin 54 restricts the position of the limiting arm 52, thereby restricting the position of the cover plate 55. The second spring 56 improves the stability of the pin 54 inserted into the round hole 53, preventing the pin 54 from falling out of the round hole 53 due to shaking.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
